The accelerated integration of OT (operation technology) and ICT (information and communication technology) into OICT is the general trend, which will surely bring subversive changes to the traditional operation management and control system of the steel industry, gradually replace the traditional OT technology and its networking form, and pass the Full connection, virtualization (digitalization), cloudification, and closed-loop control can achieve global optimization of resources.
The iron and steel industry has the characteristics of continuous process, heavy assets, information-intensive, high energy consumption, high emission, harsh working conditions, high risk, strong interference, and wide range of wireless communication signal shielding points. more stringent requirements.
At present, the steel operation management and control system usually consists of 5 levels: L0 - perception and execution equipment level, L1 - basic automation control level (PLC), L2 - process computer control system level (PCS), L3 - manufacturing execution system level (MES), L4 - Enterprise Resource Planning Level (ERP).
